Our friend Christian Gebhardt from SportAuto.de had the privilege to take a closer look at the recently launched 2013 Porsche 911 GT3 and GT3 Cup in Geneva.

The road-legal 911 GT3 has a six-cylinder 3.8-liter boxer engine with 475 HP (349 kW) and 438 Nm (324 lb-ft) linked to a 7-speed, dual-clutch gearbox and a locking differential. It needs 3.5 seconds from 0 to 62 mph (100 km/h) and will keep on accelerating until it reaches 195 mph (315 km/h).

It rides on 20-inch forged alloys with central locking hubs and benefits from a center-mounted double exhaust system. It's the first Porsche ever to come with an active rear wheel steering system which can steer the rear wheels in the opposite or same direction of the front wheels for better agility.

Prices start from 137,303 EUR and will go on sale in Germany this August.

As for the track-only 911 GT3 Cup, this has a 3.8 flat-six with 460 HP (338 kW) mated to a 6-speed "dog-type" gearbox controlled with shift paddles mounted on the steering wheel. It comes with single-piece racing wheels shod in Michelin racing slicks and packs a rear wing, center-mounted exhaust and a front splitter.

The car will race in the Porsche Mobil 1 Supercup this year and costs from 181,200 EUR.
